magnetic bearing वाक्य

The active magnetic bearing allowed the elimination of oil reservoirs on compressors for the NOVA Gas Transmission Ltd . ( NGTL ) gas pipelines in Alberta, Canada.
Spinning a thousand revolutions per second on nearly frictionless magnetic bearings, they convert electrical energy to motion and back again through a system of magnets and coils.
As a result, most magnetic bearings are active magnetic bearings, using electromagnets which require continuous power input and an active control system to keep the load stable.

Masses travelling in circular tracks on the inside of the sphere, at velocities significantly greater than orbital velocity, would press outwards on magnetic bearings due to centrifugal force.

In 1987, Estelle Croot further improved active magnetic bearing technology, but these designs were not manufactured due to expensive costs of production, which used a laser guidance system.
By carefully recording distances ( time or paces ) and magnetic bearings traveled, one can plot a course and return to one's starting point using the compass alone.
Some compasses allow the scale to be adjusted to compensate for the local magnetic declination; if adjusted correctly, the compass will give the true bearing instead of the magnetic bearing.
Plain bearings typically handle only lower speeds, rolling element bearings are faster, followed by fluid bearings and finally magnetic bearings which are limited ultimately by centripetal force overcoming material strength.
In a combined design, permanent magnets are often used to carry the static load and the active magnetic bearing is used when the levitated object deviates from its optimum position.
